SGP/EBBR/E15 - Net Radiometer not level
DataStreams:sgp30ebbrE15.b1, sgp5ebbrE15.b1
Description:
The EBBR net radiometer at E15 was suspected to be off of level
               because the daily peak net radiation was recorded later than it 
               was recorded by the SIRS.

               Site Ops found the EBBR net radiometer at E15 was significantly 
               off of level (1/2 bubble tipped to the north).  Adjustment of 
               the level improved the comparison of peak time with the 
               co-located SIRS.

               There was no significant effect on the sensible and latent heat 
               fluxes.

SGP/EBBR/E15 - Soil Moisture Coefficients Incorrect
DataStreams:sgp30ebbrE15.b1
Description:
The soil Moisture coefficients used for E15 were incorrect from the time of
installation of the system in program version 8.  On 9 July 02 parameter 4  (an offset 
value) of program step 136 was changed from 9.5264 to the correct value 0.95264 (this error 
had been made by the vendor). The error masked the real problem (wrong soil type) and 
after 9 July 02 resulted in very low soil moisture measurements.  The coefficients used were 
for coarse sand.  On 28 Sep 04 I visited the E15 site and found the soil type a fine 
sandy clay or fine sandy loam.  I changed the coefficients  at 1509 GMT to those for a very 
fine sandy loam; this produced reasonable soil moistures for the soil type.

The old coefficients in parameters 4 through 9 for step 136 of the program were: 0.95264, 
-6.7859, 36.224, -58.619, 25.073, 4.2278

The new coefficients are: 10.241, -27.943, 49.523, -12.648, -52.643, 38.054

SGP/EBBR/E15 - Soil Heat Flows Undermeasured, and Latent and Sensible Heat Fluxes 
Overstimated
DataStreams:sgp30ebbrE15.b1
Description:
Use of the wrong soil type soil moisture coefficients caused soil moisture to be greatly 
undermeasured (a typical wrong value was 4% instead of the correct 17%), soil heat flows 
to be undermeasured, and sensible and latent heat fluxes to be overestimated.

Soil heat flow plate outputs were undermeasured by up to 10%, change of energy storage was 
undermeasured by up to 80% and total soil heat flow was undermeasured by up to 50% as a 
result. This would result in approximately a 5% overestimation of both sensible and 
latent heat fluxes.

SGP/EBBR/E15 - Improved EBBR CR10 Program
DataStreams:sgp30ebbrE15.b1
Description:
Effective 20050329.1900, the EBBR.E15 CR10 program was revised to improve 
the quality of the primary measurements as follows:
   
1) An RMS procedure is used to determine max and min limits of acceptable
soil heat flow.  This is applied to the individual soil sets.  Measurements
outside the limits are rejected and the measurements within the limits are
used to calculate the average soil heat flow.
   
2) Max and min limits are used to determine incorrect values of net
radiation, sensible heat flux (h), latent heat flux (e), and automatic
exchange mechanism (AEM) signal.  If AEM signal is outside the limits, h 
and e are set to 999s.  If net radiation is outside the limits, h and e are 
set to 999s. If h or e are outside the limits, h and e are set to 999s.
   
Virtually no incorrect soil measurement will affect the primary 
measurements of h and e.
   
By setting h and e to 999s, it can be easily seen that the primary 
variables are incorrect; no other interpretation is possible.
   
Prior to 20050329, the improved CR10 program was NOT in effect.  DQRs have
been submitted for known instances of incorrect soil measurements which
affected the quality of the primary measurements of h and e.
   
Note: the DQR begin date is the begin date of the sgp30ebbrE15.b1 data
stream.  The earlier version of the CR10 program was also used on previous
EBBR datastream names (e.g. sgp30ebbrE15.a1).

Description:
During EBBR 3 month checks the Automatic Exchange Mechanism is disabled 
(reflected by home signals near zero) so that the two aspirator units
can be placed at the same height.  The measurements during these periods 
do not produce correct outputs of bowen ratio (bowen), sensible heat flux (h), 
or latent heat flux (e), nor do the air temperature and relative humidity 
measurements indicate correct gradients.  Checks performed before or after the 
AEM is disabled also lead to some incorrect data.  Incorrect 5, 15 minute and 
half hour data occurs for periods indicated.

SGP/EBBR/E15 - EBBR Net Radiometer Domes Pierced, Water Inside - Data Affected
DataStreams:sgp15ebbrE15.a1, sgp30ebbrE15.a1, sgp5ebbrE15.a0
Description:
The upper dome of the EBBR net radiometers was punctured.
After the puncture, water collected in the top and/or bottom dome.  The
water was removed and the dome was replaced during PM visits. 

 In some cases, the puncture and water resulted in incorrect data. 
Comparison with net radiation values from surrounding EBBR sites and the
SIRS is neccesary to determine if the EBBR net radiation data 
are correct or incorrect.

It is often difficult to tell from the data when the punctures occurred,
but they would have existed for no more than 2 weeks, since the domes
are checked during each two-weekly PM visit.

Incorrect net radiation data results in the latent heat flux and
sensible heat flux also being incorrect.

Description:
During this period the barometric pressure exhibited increasingly larger,
and unatural, diurnal fluctuations.  This has been observed at other sites
previously.  The sensor was replaced on April 21.  The diurnal fluctuations
had only a minor effect on the calculated fluxes of latent and sensible
heat; the fluxes are not incorrect as a result of the problem.

SGP/EBBR/E15 - Left T/RH Probe Temperature Too Large
DataStreams:sgp15ebbrE15.a1, sgp30ebbrE15.a1, sgp5ebbrE15.a0
Description:
Beginning in February, the temperature of the left T/RH probe reported too
high a value at some times.  The frequency of the problem increased with
time until 28 April at 1520 GMT, when a defective probe was installed; the
latter probe temperature indicated very high values.  This continued until
1 May at 1530 GMT when a working probe was installed. Times of incorrect 
humidity probe temperatures can be determined by comparing 5 or 30 minute 
values of air temperature and humidity probe temperature; at these times the 
calculated bowen ratio, and the fluxes of latent and sensible heat are 
incorrect.

The incorrect variables were:

5  minute:  thum_top, thum_bot, vp_top, vp_bot
15 minute:  rr_thum_l
30 minute:  thum_top, thum_bot, vp_top, vp_bot, bowen, e, h

SGP/EBBR/E15 - Temperatures Incorrect
DataStreams:sgp15ebbrE15.a1, sgp30ebbrE15.a1, sgp5ebbrE15.a0
Description:
Poor contact of the reference temperature probe leads to the J-panel or
multiplexer caused frequent offscale and incorrect values of the reference
temperature.  All other temperature measurements (air, soil, and humidity 
probe) depend on the reference temperature for a correction.  Therefore all
temperature measurements are frequently offscale and incorrect during the 
specified period.  The data clearly shows the offscale times.

  • Reference Thermistor Temperature(tref)
  • bottom air temperature(tair_bot)
  • top air temperature(tair_top)
